Bridge Type Scraper Reclaimer Overview

What Is a Bridge Type Scraper Reclaimer

A bridge type scraper reclaimer helps move and mix lots of bulk material in a stockyard. The machine sits on a bridge that goes over the pile. It moves on tracks, so it can travel along the whole pile. Its main job is to pick up material and put it onto a conveyor for more work or to move it somewhere else.

This machine looks different from other reclaimers. It does not use bucket wheels or drums. Instead, it has a scraper chain with buckets or blades. The chain moves along the bridge and scrapes material from the pile. Then, it puts the material onto a conveyor. You can see the main features of this machine in the table below:

You will find bridge type scraper reclaimers where people need to handle coal, ore, limestone, or other bulk materials. These machines help keep work going by moving and mixing material quickly.

How Bridge-Type Scraper Reclaimer Works

Operating Principles

A bridge-type scraper reclaimer moves over the top of a stockpile. The bridge sits on rails and goes along the pile. The scraper chain has blades or buckets. It moves back and forth across the bridge. This chain scrapes material from the pile’s surface. It pushes the material to the middle. The material falls onto a feeding belt conveyor under the bridge.

You can change how fast the scraper chain moves. You can also control how fast the bridge travels. This lets you pick how much material you want to reclaim. Many reclaimers have computer controls. These controls help you set the reclaiming speed. They also let you watch how the machine works. Some machines can reclaim up to 4,000 tons each hour. There are single, twin, or double boom models. These choices help you work with different yard shapes and materials.

A bridge type scraper reclaimer is good for even blending. The scraper chain moves thin layers of material. This mixes the material as it moves. You get a more even product. The design keeps dust low. It also stops the material from separating. The machine can work for a long time without stopping.

Note: Automatic operation helps you blend better. This keeps your bulk material quality steady.

Main Components

A bridge-type scraper reclaimer has many important parts. Each part does a special job. The table below shows the main parts and what they do:

These strong parts make the bridge type scraper reclaimer last a long time. The machine uses tough steel and special materials for the scraper chain and blades. This means you do not need to fix it often. You also get better performance.

• The girder and tower frame make the machine strong.
• The material rakes and scraper group move the bulk material.
• The oil cylinder lets you move the rakes quickly.
• The feeding belt conveyor helps the material leave the pile smoothly.

Some reclaimers have trippers. These let you skip the machine and send material straight from unloading to loading. Some models can work with piles on both sides using booms. Back stacking helps you handle material better.

Tip: Pick a bridge-type scraper reclaimer with automatic controls and speed settings. This helps you blend well and makes your work easier.

Strong parts, smart controls, and good design make the bridge-type scraper reclaimer a great choice for bulk material handling. You get high capacity, less fixing, and good blending every time you use it.
